Finally, the selection of the material of deflector 100 must fall into subsequent lamination process or identical behaviour in photovoltaic module Make to significantly change at a high temperature of can reach in life cycle on the material of associated mechanical and optical characteristics (i.e. transparency).

Additionally, it is necessary to which it is emphasised that the use of transparent material also allows in the embodiment shown in fig. 1 with two-sided module Mode uses deflector 100.

As shown in Fig. 2, in the second embodiment of deflector 100 according to the present invention, on the other hand, reflecting surface 101 With direction orientation opposite relative to each other, but the sequence 102 of reflecting surface 103 is not present, however on the other hand, the reflection table The sequence 102 in face 103 is present in first embodiment.Therefore, each of two reflecting surfaces 101 have opposite first End, engages with the first end of reflecting surface 101 corresponding thereto in corner point, and with engaging with flat base wall 104 Second end, the flat base wall 104 form the back side of solar energy deflector module.

The embodiment of collector shown in Fig. 2 can also be made in this way, i.e., deflector 100 is by transparent material It is formed, it is then anti-from 100 inner side of deflector because solar radiation in this way can initially enter deflector 100 from bottom wall 104 It is mapped on reflecting element 101 and/or reflecting element 103.

Moreover it is preferred that the refractive index of the material of deflector 100 is less than or equal to the refractive index of coating 202, and Less than or equal to for deflector 100 to be engaged to the refractive index to adhesive or glue on the groove of coating 202.

Finally, the selection of the material of deflector 100 must fall into subsequent lamination process or identical behaviour in photovoltaic module Make to significantly change at a high temperature of can reach in life cycle on the material of associated mechanical and optical characteristics (i.e. transparency).

Additionally, it is necessary to which it is emphasised that the use of transparent material also allows in the embodiment shown in Figure 2 with two-sided module Mode uses deflector 100.

As shown in figure 3, in the third embodiment of deflector 100 according to the present invention, with embodiment shown in Fig. 2 Similar mode, reflecting surface 101 are orientated with opposite directions, and each reflecting surface 101 has first end, It is engaged with the first end of another reflecting surface 101, to form angle at top outstanding, and there is second end, another On the one hand engage with the sequence 102 of reflecting surface 103, the sequence 102 of the reflecting surface 103 therefore positioned at lower height and It is corresponding with the back side of photovoltaic module when in use.

The fourth embodiment of deflector 100 according to the present invention is shown in FIG. 4.Fourth embodiment and above-mentioned third are real It is similar to apply example.Fourth embodiment also has the reflecting surface 101 being orientated with opposite directions, and each reflecting surface 101 have first end, engage with the first end of another reflecting surface 101, to form angle at the top of protrusion, and have There is second end, engaged with the first end of corresponding connection surface 105, to be taken relative to two inclined directions of primary reflection surface 101 To form acute interior angle.The second end of connection surface 105 has reached the sequence of the reflecting surface 103 positioned at lower height 102, and it is corresponding with the back side of photovoltaic module when in use.

There is reflecting surface with the back side in front in each of above-mentioned third and fourth embodiment；This feature is very It is important, because these collectors are designed to two-sided photovoltaic inside modules, that is to say, that, it is characterised in that battery can be collected The solar radiation on two sides, and having is transparent front shroud and back shroud.

Finally, Fig. 5 shows the 5th embodiment of collector according to the present invention.In the configuration, reflecting surface 103 Sequence 102 is engaged with flat base wall 104, which substantially connects with the angle point formed by the joint of reflecting surface Touching.

The mode that the embodiment of collector shown in fig. 5 can also be overturn makes, that is to say, that the bonding of bottom wall 104 or weldering It connects in the groove of coating 202.In this case it is necessary to deflector 100 be formed using transparent material, because so too Sun radiation can initially enter deflector 100 from bottom wall 104, then from the offside reflection in deflector 100 to reflecting element 101 And/or on reflecting element 103.

Moreover it is preferred that the refractive index of the material of deflector 100 is less than or equal to the refractive index of coating 202, and Less than or equal to for deflector 100 to be engaged to the refractive index to adhesive or glue on the groove of coating 202.

Finally, the selection of the material of deflector 100 must fall into subsequent lamination process or identical behaviour in photovoltaic module Make to significantly change at a high temperature of can reach in life cycle on the material of associated mechanical and optical characteristics (i.e. transparency).

Additionally, it is necessary to which it is emphasised that the use of transparent material also allows in the embodiment shown in fig. 5 with two-sided module Mode uses deflector 100.

According to preferred embodiment, collector as described herein is preferably made of thermoplastic material, that is, passes through injection moulding It is used to process the other technologies of plastic material known to technique or those skilled in the art to be made.Material for collector Selection can also fall into and will not change on relative nature and the material of physical characteristic (i.e. mechanical property) over time, Especially be mounted in the module when solar collector lamination during or the accessible temperature during life cycle Under.

On the other hand, reflecting surface is by entire solar radiation spectrum (at least in visible spectrum and infrared spectroscopy) High reflection material is made；Preferably, reflecting surface by silver or alternatively by aluminium (its as the first alternative solution, price is lower, But performance is lower) it is made, or be made of gold (as alternatively possible theoretical property alternative solution, although it is from technical standpoint From the point of view of be effective, but its cost wants much higher).

The prior art although other known technologies can be used, preferably by being referred to as " sputtering (sputtering) " To make reflecting surface.

As shown in fig. 6, photovoltaic module 200 includes the alternate sequence of adjacent photovoltaic cell 201, these adjacent photovoltaic cells 201 are collected between two deflectors 100 relative to each other, in the example by photovoltaic module 200 shown in the example in Fig. 6 In son, each correspond to the deflector similar with the deflector of first embodiment shown in Fig. 1.

Each deflector 100 is closed in plane coating 202, which is also transparent to solar radiation 's.The front cover and rear cover of the formation photovoltaic module 200 of plane coating 202.It is between the first coating and the second coating 202 Clearance layer 203 is equipped with photovoltaic cell 201 and bus 204, i.e. electrical interconnection element in clearance layer 203.Encapsulating material setting In gap layer 203, which is electrically insulated two coatings 202, and also photovoltaic cell 201 and bus 204 are isolated.

Plane coating 202 also works in photovoltaic module 200, because the radiation reflected by reflecting surface will be to be greater than Interface between the incidence angle irradiation frontal plane coating 202 and air of critical angle, thus reflected again with total internal reflection, Until reaching photovoltaic cell in end.

Each coating 202 can accommodate the reflecting element in its groove, and the reflecting element is designed to collect and wear Cross the solar radiation of coating.Therefore, the shape or outline of groove possessed by each coating 202 are in the receipts of installation Storage, or with the collector be under any circumstance compatible.Although being not shown in Fig. 6, coating 202 can It is made together with relevant inner surface, that is to say, that contacted with clearance layer 203, and also comprising being modeled according to quality, appropriate The groove of ground Selective type, as anti-in the interface between the material being in contact with it to coating 202 and on an internal surface The function for the contrast penetrated, the material include such as encapsulating material and/or adhesive or glue 300.

Although being not shown in Fig. 6, exist if it is necessary, deflector 100 can have not to be positioned in layer 202 Groove in but the part that extends in clearance layer 203, wherein encapsulating material also is located in the clearance layer 203.

In this case, deflector 100 can have groove on bottom wall 104, which is configured to receive bottom Any interconnection element between photovoltaic cell is defined as " conducting wire " or " band " with technical term, it is preferable that unlike in deflector 100 be individually located in groove present in coating 202 in the case where make route turning like that.

In addition, as shown in fig. 6, can use preceding coating 202 and/or rear coating 202 to manufacture two-sided photovoltaic module, The coating accommodates any deflector elements in five embodiments shown in Fig. 1 to Fig. 5 in its groove.

Photovoltaic module (not showing) can also be made with the photovoltaic cell 201 of traditional single-sided type, that is to say, that its Solar radiation can only be collected in one side (usually front).In this case, rear coating can be flat or by not Same (even opaque) element replaces.

During manufacturing photovoltaic module 200 according to the present invention, by adhesive or glue 300 or allow not Any other welding technique that deflector 100 and coating 202 are engaged in the case where being damaged by thermal pulse, will at corresponding recesses Deflector 100 is bonded to coating 202.Described adhesive or glue (at least in visible spectrum and infrared spectroscopy) are for the sun Radiation is transparent.In addition, the refractive index of adhesive or glue is preferably equal to or less than the refractive index of coating 202.

For by deflector 100 engagement on the groove of coating 202 adhesive or glue 300 must also be able to completely It is optical coupled to realize full of the space between reflecting element and its groove welded, without on the surface welded Between there is out-of-flatness or defect.Finally, the selection of adhesive must fall into the subsequent lamination process or phase in photovoltaic module The material of associated mechanical and optical characteristics (i.e. transparency) will not be significantly changed at a high temperature of can reach in biconditional operation life cycle On.

In the operative configuration described in Fig. 6, it can also check that the plate in outer rim does not have reflecting element, on the contrary, the reflection Element is maintained in the shell of module further away from edge to sufficient degree, to protect them from vapor and exotic The infiltration of matter.

Therefore, in outside, the conventional photovoltaic modules of photovoltaic module 100 according to the present invention and not deflector seem phase Together.

As being briefly described above, in two-sided module as shown in FIG. 6, and if it is necessary, also in attached drawing In in unshowned single side module, all preferred positions of electric interconnection element of bus 204 and (more generally) photovoltaic cell 201 In the side of photovoltaic module 100, and it is advantageously enclosed in the electric insulation layer for being present in the subsequent encapsulating material of reflecting element In.

In the subsequent configuration with electric interconnection element of reflecting element so that can also be as shared by electric interconnection element According to region in collect solar radiation (this conventional photovoltaic component in no convergent component (concentration element) In be impossible), photovoltaic module total surface under the same conditions, advantageously allow for obtaining for collecting solar radiation The extension in region, to improve whole efficiency.

Groove is along entire coating 202.Therefore, if groove is present in all four sides of battery, each is recessed Slot will be intersected by four edges that its edge is formed with other grooves in each battery.Reflecting element can also be worn using it Saturating shape occupies entire inner space.An example is shown in Fig. 7.In the figure, it can be seen that how to use All reflecting elements 101 in groove of the element of single grille-like to make coating 202 to be placed on, or equally It makes its length and is equal to the reflecting element for accommodating the length of groove of reflecting element.Reflecting element as shown in Figure 7 can be in accessory 211 In intersect with other elements, formed along groove whole length extend single reflecting element, without consider with other reflectors The quantity for the intersection that part is formed, to form the grid plate surface for including projected square part 210.

Finally, Fig. 8 a shows the solution suitable for deflector 100, which has pseudo- rectangular photovoltaic Intersect in the case where battery 201.The rectangular photovoltaic cell of puppet is not rectangular, has bevel edge angle 213.Fig. 8 a is schematic Ground indicates the first solution, wherein the region in the edge for the reflecting element that flat reflecting mirror 400 occupies intersection 401, which is not occupied by pseudo- rectangular cell.

The feasible solution of another kind shown in Fig. 8 b includes extending reflecting element with inclined mirror 402, this inclines Oblique reflection mirror 402 occupies the region not occupied by pseudo- rectangular cell in edge.

Fig. 9 shows the construction variant of presented all embodiments comprising coating 202 is divided into two tools There is specific and different function individual component.

Embodiment shown in Fig. 9 includes the completely flat coating 202 in surface 302, for example, but not limiting the present invention Range in the case where, the regular solar glass used in the conventional photovoltaic modules of no convergent component " float glass process (float) ". Flat coating 202 lower section place an internal element 304, the internal element have with provided in the embodiment it is recessed The similar groove of slot, such as to the sun spoke in spectrum used in photovoltaic cell (such as PMMA or polycarbonate pc) The thermoplastic with high-transmission rate is penetrated to be made.By two flat covering layer elements 202 and there is groove using the prior art Bottom internal element 304 bond/weld together, such as (but not limiting the scope of the invention) passes through position by laminating technology The sheet material (for example, commonly used in EVA sheet of lamination photovoltaic module) of the encapsulating material in gap between two elements, such as It is necessary to also be bonded/welded together using the single laminating technology of entire photovoltaic module and its shell.If any must It wants, has the periphery that reeded internal element 304 can be not extend to cladding element 202, thus at the edge of photovoltaic module 301 On leave peripheral space, for wherein position with the insulation of exterior materials, this type of insulation has been traditional photovoltaic mould It known in block manufacture and commonly uses, so that if it is necessary, allowing to carry out further degree to all elements in cladding element 202 Insulation and protection.Implementation shown in Fig. 9 is illustrated the production example of the substitution of embodiment shown in Fig. 6, but very It is apparent that this variation can be applied to all embodiments presented.The variant embodiments are particularly useful, to fill It point utilizes related to the various requirement of coating of coating and inner surface lower grooves for manufacturing outer surface upper module Different materials particular characteristic；If using while having the discrete component there are two types of function, it is necessary to use a kind of exist The material traded off between being required as defined in the function of two kinds of execution.On the other hand, if two individually members can be made Part can then have for the selection of each of two elements and execute with for coating 202 or internal element with groove 304 The relevant optimum performance characteristic of specific function material.In particular, mechanical strength property and the screen for preventing exterior materials from permeating Hinder it is critically important for coating 202, other than the stability of these requirements at any time, the light that is also used with photovoltaic cell The reduced roughness of the good transmissivity of solar radiation in spectrum and over time holding outer surface is (even if be subjected to outer Portion's substance) ability it is related.Such as but in the case where not limiting the scope of the invention, by regular solar glass " float glass process " with And it is wanted for example, by PMMA (especially for the major function for the barrier for preventing exterior materials from permeating) these are best accomplished It asks.On the other hand, the dimensional tolerance of groove particularly importantly can be made as far as possible for internal element 304 with groove It is small, and the shape and size relative to the single groove being located in identical internal element 304 with groove, have maximum Design alternative freedom degree.For example, by PMMA, (it can be processed in the groove of any shape, use known processing thermoplastic Property plastics technique, for example, injection molding technique, with very small tolerance) rather than for example common solar energy glass (warp Go through and groove be made as " figured plate glass " or " rolled glass "), it can preferably reach these requirements.

Although being not shown in Fig. 9, internal element 304 can be to relevant inner surface (that is, and clearance layer 203 contact and also comprising moulded according to the quality, groove that properly selects type) be made together, as with to coating The function of the contrast of the internal reflection at the interface between 304 and the material that is in contact with it on an internal surface, the material includes example Such as encapsulating material and/or adhesive or glue 300.

Figure 10 shows the construction variant of presented all embodiments comprising deflector 100, in other embodiments In those of formed into Fig. 5 to Fig. 1 related, the deflector 100 is not positioned over layer elements 202 or internal element 304 Present in groove, but between the photovoltaic cell 201 in clearance layer 203.

Embodiment shown in Figure 10 includes all reflecting elements that production will place on a single element in the form of a grill 101 and/or 103, or more elements are equally manufactured, as shown in fig. 7, these elements can mutually be handed over by accessory 211 Fork finally manufactures the single assembly element having with grid same shape and function.

For embodiment shown in Fig. 10, because without using the reeded coating 202 of tool, therefore Internal periphery can be with It is flat.In addition, the deflector 100 being located in clearance layer 203 has flat in-profile in turn, can be made has It can be arranged side by side with photovoltaic cell 201, the shape without generating any pressure or mechanical stress on the surface thereof: special It is not, can be by its thickness since the thickness of deflector 100 is greater than the thickness of the other elements in coating 202, essence The thickness (overall thickness of encapsulating material) of upper determining clearance layer 203 and the volume of deflector 100 are in the thickness of clearance layer 203 Position, so that it is guaranteed that the height in these spaces and the space that occupies of photovoltaic cell 201 of the inside by being located at clearance layer 203 Height is not overlapped.In brief, between deflector 100 and photovoltaic cell 201 without apparent mechanical disturbance, the latter is not and not There are stress different or bigger in the conventional photovoltaic component of deflector.

Therefore, during being used for assembling photovoltaic modules, preferably will be (if necessary) mutual in series or in parallel After the photovoltaic cell of connection is positioned, grid (all reflecting elements 101 and/or 103 comprising constituting deflector 100) can In space between photovoltaic cell 201.

Embodiment shown in Figure 10 includes in reflecting element 101 present on the front and back of deflector elements 100 And/or 103；This feature is extremely important, because these collectors are designed, is preferably used for two-sided photovoltaic inside modules, That is, it is characterised in that battery can collect the solar radiation on two sides, and having is transparent front shroud and rear cover Plate.

Embodiment shown in Figure 10 includes the deflector elements 100 in two faces, substantially by the embodiment according to Fig. 1 Two deflectors 100 engage formed.Although not shown, but can also be used together with embodiment shown in Figure 10 by scheming Two deflectors engagement in other embodiments shown in 2 and Fig. 5 and the implementation of deflector elements 100 essentially formed Example.Although not shown, but Fig. 3 and deflector elements shown in Fig. 4 100 can also be used together with embodiment shown in Fig. 10 Embodiment.

Although not being shown in FIG. 10, can be used include the deflector elements 100 formed by transparent material reality Example is applied, it is then anti-from 100 inner side of deflector because solar radiation in this way can initially enter deflector 100 from bottom wall 104 It is mapped on reflecting element 101 and/or reflecting element 103.

In addition, the refractive index of the material of deflector 100 is less than or equal to the refractive index of coating 202, and it is less than or waits In for deflector 100 to be engaged to the refractive index to adhesive or glue on the groove of coating 202.

The selection of the material of deflector 100 must fall into subsequent lamination process or same operation service life in photovoltaic module On the material that associated mechanical and optical characteristics (i.e. transparency) will not be significantly changed at a high temperature of can reach in period.

Additionally, it is necessary to which it is emphasised that the use of transparent material also allows two-sided module in the embodiment shown in fig. 10 It is middle to use deflector 100.

Although being not shown in Figure 10, the embodiment comprising deflector elements 100 can be used, advantageously according to Fig. 1 to Fig. 5 Embodiment, only on one face include deflector embodiment；These collectors are designed to be preferably used for photovoltaic module Inside, it is characterized in that photovoltaic cell can only collect solar radiation on one face.

Embodiment shown in Fig. 10 includes the deflector 100 for several volumes 205 being superimposed upon on photovoltaic cell 201.This is folded 205 are added to be in order to avoid generating discontinuity zone between deflector 100 and photovoltaic cell 201, solar radiation passes through these areas Domain and can not be collected.Therefore can be discontinuous to avoid these by superposition 205, for example, if mutually similar in photovoltaic module Between the element of type, the change in size that may occur especially between deflector 100 or between photovoltaic cell 201, and at it Spatial position respective distance may change in the case where, can be discontinuous to avoid these.Superposition 205 can only be in deflector Executed on 100 face, for example, upper in front can only execute, as shown in Figure 10, or in front with below on be carried out.

The superposition 205 of deflector 100 on photovoltaic cell 201 can also be used for deflector 100 being superimposed upon inside battery On any conducting element 204 and/or 206, and/or for the interconnection between several photovoltaic cells；The element of these types, example Such as, in technical term be also referred to as " finger-shaped material (finger) ", " bus " 204, " band " or " conducting wire " 206, due to they Photovoltaic cell active region (i.e. it is capable to absorb and convert solar radiation photovoltaic cell region) before cause Shielding (screening) so that a part of solar radiation will not be collected, but be reflected to the outside of current module.If Conducting element in battery and/or the conducting element for the interconnection between several photovoltaic cells are influenced by deflector 100, The radiation in these regions is then incident on before reaching these elements, will be collected from deflector 100, described without generation Collect failure, it is advantageous under conditions of photovoltaic module total surface area is equal, be used in collection for the solar radiation of acquisition Area expands, to improve whole efficiency.Although being not shown in Figure 10, reflecting element 101 and/or 103 can also be made Be located in overlapping 206 on the surface of deflecting plates 100 so that the solar radiation of these interior zones can also be collected, this be by Caused by any exposure caused by the size and spatial position change of the element in photovoltaic module.
